Seltzer water

S mixture is a combination of two or more substances in which each substance retains its properties. Most materials we encounter are mixtures mixtures of elements, mixtures of compounds, or mixtures of elements and compounds. Stainless steel, for example, is a mixture of the elements iron, chromium, nickel, and carbon. Seltzer water is a mixture of the liquid compound water and the gaseous compound carbon dioxide. Our atmosphere, as Figure 2.14 illustrates, is a mixture of the elements nitrogen, oxygen, and argon plus small amounts of such compounds as carbon dioxide and water vapor. 

Two plastic bottles of fresh seltzer water are opened. Three-fourths of the first bottle are poured out for drinking and only one-fourth of the second bottle is poured. Both bottles are then tightly resealed. The next day they are both reopened but one is less fizzy. Which one Why ... 

C. A. Snyder and D. C. Snyder, "Simple Soda Bottle Solubility and Equilibria," /. Chem. Educ., Vol. 69,1992,573. Bromocresol green indicator, added to a glass bottle of seltzer water, changes color from yellow to green to blue as carbon dioxide concentration is decreased. Observations are related to temperature and pressure effects on gas solubility, and LeChatelier s principle is applied to the equilibria involved. 

The original recipe calls for 2 tablespoons of chocolate syrup, 2 cup of whole milk, and 1 cup of seltzer water, but I ve modified that significantly in an equally delicious alternative that packs more of cocoa s polyphenols and eliminates the sodium from seltzer water. 

Some acids are quite harmless, and most of us swallow acidic substances on a day-to-day basis. Soda and seltzer water contain carbonic acid. Orange juice, oranges, lemons, and limes contain citric acid. Vinegar contains acetic acid. So, not all acids are dangerous.

Gases in liquids are easily measured when you know the pressure, volume, and temperature of the gas. Seltzer water and ammonia water are two good examples of solutions of a gas in a liquid. Seltzer, which is carbonated water, consists of pressing the carbon dioxide gas into the water. The bubbles in beer or sparkling wines are also due to carbon dioxide, but the C02 is a natural product of the fermentation process. Ammonia water, also called ammonium hydroxide solution, is made from ammonia (NH3) being pressed into water. It is used as a weak base and as a cleaning material. 

Johann Carl Friedrich Meyer (Stettin 1733-20 February 1811), Court Apothecary in Stettin, besides his papers on colloidal silica (see p. 188), hydrofluoric acid (see p. 215), the non-convertibility of silica into alumina (see p. 568), and the preparation of sodium carbonate from common salt (see p. 562), investigated the solubility of lead in sulphuric acid and the action of acids on strontia, and analysed minerals. He prepared artificial Seltzer water. He found that Siberian native iron dissolves in dilute sulphuric acid to a green solution, which becomes blue with ammonium chloride. Proust later showed that native (Peruvian) and meteoric iron contain nickel. Meyer s supposed new metal, hydrosiderum, he showed himself was iron phosphide (seep. 194). 

Red cabbage contains a material that makes an acid-base indicator. Place two cups of chopped red cabbage in a blender, cover with boiling water, and blend. Use a coffee filter to filter out the plant material. Add the indicator to materials like lemon juice, baking soda, antacids, and seltzer water. The indicator will turn red/purple/violet in the presence of acids and blue/green/yellow for bases. 

SELTZER WATER. The bubbling action in the seltzer is what makes it an effective stain fighter. Before pouring on a small amount of fizzy water, blot and dab urine stains with paper towels. Once the liquid has stopped fizzing, blot the spot again and repeat as necessary. For a fresh stain, this may be all the treatment you need. For old or set-in stains, consider this a pretreatment. Allow the carpet to dry, then treat with the baking soda method (Step 2).
